Without an appointment, I randomly selected a place and waited for a friend there. This time Jacky, a university classmate whom I had not seen for two years, appeared at the chosen location at 16:38. He asked me, "How do you know I'd be here?" I told him, "I really don't know... but I've been waiting for you here for a long time!"

I drew a horizontal line on a map of Victoria Harbour, and the line went through a total of five intersections on the coastline. I filled up plastic bottles with seawater from those intersection points, each the same amount, and then I put the five bottles of seawater at home - A continuous sea level emerged.

I stood in front of a 13-storey building in Sham Shui Po and waited for all the residents to fall asleep. The photographs were taken at 22:38／01:40／02:36／04:09／05:04. A person in the building remained awake throughout the night, we ended up wasting a night together while being on opposite sides of the street.
